VTICK ADJUSTMENT FORE OIL-BURNERS.

"T all whom it may concern:

'Be it known that I, Jacoe SwALLow, a

.CltiZGD of the United States; residing at'Los 7 'Angeles, in the countyofLos Angelefs and *State of California, have invented new and usefulImprovements in Tick 'Atl ustme nts. v "for Oil-Burners ofwhichthe'followlngis specification.

This invention relates to a wick adjustment for oil burners andparticularly pertains to a device for adjusting cylindrical wicks in oilstoves, lamps, and the like.

In adjusting the cylindrical wicks in oil stoves and lamps by themechanism now commonlyemployed, binding of the wick] occurs, especiallywhen it is short, which inhibits its being readily raised and loweredand thereby prevents accurate adjustment and regulation of the flame.

It is the object of this invention to overcome the above difiiculty byproviding a mechanism which will operate on opposite sides of thecylindrical wick casing so as to equalize strains thereon and to impartpropelling movement to the wick and its casing in such manner as tocompletely obviate binding of the wick and permit ready adjustmentthereof.

Another object is to provide a device of the above character adapted tobe applied to the ordinary cylindrical wick type of stoves and lamps nowin use without material alteration thereof.

Other objects will appear hereinafter.

The invention is illustrated in the accompanving drawings in which:

Figure 1 is a view of an oil stove in side elevation with parts brokenaway and showing the invention as applied. Fig. 2 is a plan view ofsame. Fig. 3 is a vertical section on the line 33 of Fig. 2. Fig. 4t isa plan view illustrating a modified form of the invention.

More specifically, 5 indicates the tank or oil receptacle of an ordinaryoil stove having an upwardly extending top 6 and formed with a centralcylindrical draft tube 7 which terminates above the top 6 and issurrounded by the usual perforated wick tube 8. The wick tube 8 extendsinto the tank 5 and is spaced from the cylinder 7 concentric therewithto form a space for the reception of the cylindrical or tubular wick 9.

The present invention resides in a means for raising and lowering thewick tube 8 Specification of Letters Patent.

and'the wick Q'therein, which means is constructed a s'follows:Extending into the top portion 6 of the tank 5 andarrangedhorizontallyalongside of'the 'wickitube 8 is a shaft 10, fitted with a hand wheel 11on its outer end and having a pair of spacedpinions 12 mounted thereonand disposed within the tank. The pinions 12 mesh with verticall'yalined perforations inthe wick tube 8'with the teeth of the pinionsextending through the perforations into engagement with the wick '9. Theshaft may be mounted in anysuitable'bearings,being here shown asextending through a tube 13 where itpasses through the wall of the topportion G'of the tank and is seated at its inner end in a bracket 14, asparticularly shown in Fig. 1. Mounted in suitable bearings and extendingparallel with the shaft 10 on the opposite side of the wick tube 8 is ashort shaft 15 which is fitted with a pair of pinions 16. The pinions 16engage the perforations in the wick tube 8 with their teeth engaging thewick 9 diametrically opposite the point of engagement of the pinions l2therewith. The shaft 15 is designed to be rotated simultaneously withthe shaft 10, only in opposite directions thereto. For this purpose theshaft 15 is geared to the shaft 10 so that when the latter is revolvedthe shaft 15 will be rotated in unison therewith.

The geared connections between the shafts 10 and 15 comprise a spurpinion 17 mounted .on the shaft 10 which mesh with an idler gear 18which in turn meshes with a. second idler gear 19 meshing with a pinion20 on the shaft 15. The gears 18 and 19 are mounted in suitable hearingson the outer face of the top portion 6 of the tank, as particularlyshown in Figs. 1 and 2, and are preferably arranged intermediate thehand wheel 11 and the pinions 12 on the shaft 10.

In the modified form of the invention shown in Fig. 4, the shafts 10 and15 are elongated to extend through the top portion of the tank 5 toreceive the gears through which shafts 10 and 15 are revolubly connectedtogether on the outer ends thereof. This latter arrangement is employedwhere it is impractical to provide an end support for the shafts 10 and15 within the tank.

In this case the shafts 10 and 15 extend through bearings formed in theupwardly projecting portion of the top tank. The

pinions 17 and 20 are of corresponding diameter and the idler gears 18and 19 correspond to each other so that when the shaft 10 is rotated theshaft 15 will be revolved therewith at a corresponding speed but in theopposite direction.

In the operation of the invention rotation of the shaft 10 operatesthrough the pinions 17, gears 18 and 19, and pinion 20, to rotate theshaft 15, as just described. The rotation of the shafts l0 and 15operate through the pinions 12 and 16 to advance or retract the wickcasing 8 and wick 9. Equal strains are thus brought to bear ondiametrically opposite sides of the wick tube 8 which serves to move thetube 9 longitudinally evenly throughout its length, thus obviatingbinding of the wickand permitting readv and accurate adjustment thereof.

What I claim is: j a

The combination with an oil stove tank formed with an upwardly extendingtop,

and a vertically reciprocal perforated wicktube extending through thetop of said tank adapted to encircle a wick, of a pair of paralleltubular bearings projecting horizontallythrough the tank top, a pair ofshafts in said bearings extending into the tank, pinions on each of saidshafts engaging the wick-tube on diametrically opposite sides thereof, aspur pinion on each of the shafts adjacent the outer ends of the tubularbearings, a pair of intermeshing idler pinions meshing with said spurpinions bearings for said idler pinions on the outer face of the tanktop, and a hand wheel on one of said shafts.

In witness that I claim the foregoing I have hereunto subscribed my namethis 22nd day of March, 1915.

JACOB SWALLOIV.
